    I am not seeing any issue with our SSL cert on https://www.jotform.com

    but can you please try changing your form iframe embed code to use our prefered secure domain, https://secure.jotform.com

    e.g from 

    <iframe allowtransparency="true" src="https://www.jotform.com/form/3100030361" ...


    <iframe allowtransparency="true" src="https://secure.jotform.com/form/3100030361"..


    Let us know if you need any help help changing that embed code on your website.
